KDDI's au Design Project yields four phones

Those crazy cats over at Japan's KDDI are back at it with another four concept handsets as part of their "au Design Project," a collaboration with various designers that's been carrying on for some time now to draw attention to their network. Coined the Infobar 2, Kaos, Cypres, and Vols (pictured), the phones aren't technically destined for production, but let's be honest: this stuff doesn't seem much more far out than garden variety Japanese mobile hardware.
